摘　　要：端板连接是轻型门式刚架梁与柱连接所采用的主要方式,在工程实践中端板变形问题急需解决。通过对仅在关键部位接触的端板连接试件进行有限元分析,对比了极限承载力、初始刚度、端板应力以及螺栓内力的变化,提出了处理端板变形的方法。End-plate connection is a main method of beam-to-column connection in gable frames of light steel structures. The end-plate deformation is an inevitable question in construction practice. This paper raises a way to treat the connection defect caused by end-plate deformation by making a finite element analysis of the connecting end-plate in key parts and also compares the changes of maximum load, original steel hardness, end-plate stress and internal force of the bolt.
